LOOP-SANDING MACHINE.

SPECIFICATION forming part of Letters Patent No. 790,458, dated. May 23, 1905.

' Application filed March 6, 1905. Serial No. 248,687.

Be it known that I, ALoNzo E. RHoADEs, a citizen of the United States, and a resident of Hopedale, county of Worcester, State of Massachusetts, have invented an Improvement in Loop-Banding Machines, of which the following description, in connection with the accompanying drawings, is aspecification, like characters on the drawings representing like parts.

This invention relates to machines for making loop-bands employed in spinning and other apparatus and it has for 1ts object the production of novel and efiicient means to mark the loop-band while the same is distended, the marking of the band being effected at a predetermined distance from its loop end. As will be manifest, the marking of the bands is effected when the bands are under like conditions of tension, so that a series of such bands subse uently used in a'frame and tion with a well-known form of loop-banding machine, the essential portions of the band holding and twisting instrumentality being substantially as shown and described in United States patent to -Weeks, No. 121,031, dated November 14., 1871. such machines the marking of the bands has been effected by a marker adapted to dip into marking liquid contained in a suitable reservoir, the marker being moved automatically out of the liquid and against the band at the proper time, the subsequent retraction of the marker usually effected by a spring causing the marker to dip suddenly andwith considerable force into the liquid,tending to splash or In my present invention, while the actuation of the -marker to mark the band is effected positively and the retraction is caused bya spring, I have rovided means to interru t and retard suc retractive movement of t e marker so that the same enters the marking liquid quietly and with very little force, so that all tendency to splash or spill the liquid is entirely overcome.

I-Ieretofore in rear elevation, showing the marker in engagement with the band to mark the same; Fig. 4 is a similar view, but showing the marker arrested or retarded in its retractive movement just about to enter the reservoir. Fig. 5 is a perspective view of the marker; and Fig. 6 is a transverse sectional detail on the line 6 6, Fig. 2, looking toward the left to show a'portion of the retarding means which control the retractive movement of the marker.

Referring to Fig. 1, the bed-plate A, the shaft B, having fast and loose pulleys C and D thereon, the revolving head W, carrying the twisting-hooks G, (onlyone being shown,) the hooks being driven by well-known gearing mounted in the head, the fixedly-mounted guide-rodsU, on which is slidably supported the loopholder or carriage J, having a loopband hook II, the longitudinally-movable shipper-rod S, having the attached belt-fork E, the rod T, having an attached stop I to engage and prevent rotation of the revolving head W while the two halves of the band are being twisted preparatory to being doubled together, the arm L, fast on rod T, the pulley P, and weight Q, are all substantially therein set forth. Collars O on the rods U 'serve as back-stops for cushioning-springs a to act against the outer end of the loopholder J when the weight Q is free to draw the same outward, as in the patent referred to. At a suitable point on the bed A is secured an upright bracket 1, having an upturned arm 2, carrying a horizontal pin 3, on

. which is loosely mounted the hub 4 (see Fig.

. I i i i 'I 5) of the band-marker, herein shown as an. arm 5, of stiff wire, secured to the hub and at its free end being bent down and then laterally, as at 6. The pin 3 and the lateral ex tension 6 are in parallelism and are located below and transversely to the band b when the latter is in position in the machine, the bracket being so located on the bedplate A that when the marker is swung into operative position the part 6 thereof will contact with the band at a predetermined pomt from the loop thereof. A bowl-like reservoir 7 is mounted on the bracket 1 in such position that the marker may be swung on its fulcrum 3 to dip the extension 6 into a marking liquid of suitable character (indicated at 8, Fig. 2) contained in the reservoir. Normally the marker remains in about the position shown in Fig. 2, and when moved to o erative position, Fig. 3, it will be manifest t at the extension 6, loaded with marking material, will be pressed against the band if" to mark the same at the proper point and at a redetermined distance from its loop then he Id on the hook H.

A depending arm 9, suitably secured to the marker-hub 4, is pivotally connected with one end of a horizontal rod 10, slidably supported in bearings 11 12, fixed on the shipper-rod S, as clearly shown in Fig. 2, and a collar 13, fast on the rod 10, near the bear ing 12, has a depending foot 14, which loosely embraces the shipper-rod, serving as an additional guide for the rod 10. Between the bearing 12 and collar 13 a spring 15 is coiled around said. rod 10, which spring serves by its expansion to retract the marker from operative position and to cause its extension 6 to dip into the marking liquid in the reservoir. A second collar 16 is adjustably secured to rod by a suitable setscrew 17, Fig. 2, and is in the path of movement of a lug 18 on the loop holder or carriage J when the latter is moved toward the head WV of the band holding-and twisting instrumentality. When the twisting of the band has moved the carriage to bring the lug 18 into dotted-line position, Fig. 2, the said lu engages collar 16 and slides the rod 10 to the right or toward the head WV, and the marker is thereby swung positively into operative position to mark the band, simul taneously compressing the spring 15. At the same time a conical collar 19 on the rod 10 is moved past a swinging catch 20, fulcrumed on the bed-plate at 21, and the catch is swung inward by a weight 22 (see Fig. 6) behind the collar.

Referring to Fig. 2, the loop-holder J is provided with a cam-plate having oppositelyinclined edges 23 24 and an intermediate flat portion 25, adapted to cooperate with the catch 20. The cam edge 23 serves to throw the catch outward and onto the flat portion 25 when the loop-holder is just beginning its movement toward the head W, so that the portion 25 will hold the catch 20 out away from the collar 19, as in Fig. 2. As the loopholder moves inward the catch will be released by the cam-plate, and it will then rest against collar 19 until the lug 18 operates the marker, as has been described, and the catch swings in behind the said collar. The band having been marked, the shipper-rod is operated, as in the patent referred to, stopping the operation of the twisting means when the band is finished. hen the band is released from the hook H, the weight Q at once and quickly returns the loop holder or carriage J to starting position, and as the lug 18 re treats the spring acts to quickly retract rod 10 and the marker. Heretofore the latter has at once returned to the liquid, and the quick plunge thereinto tends to splash or spill the liquid, sometimes spattering the marked band and also wasting the marking liquid. In my present invention, however, the retractive movement of the marker is ar rested when the return movement of the rod 10 brings the end of collar 19 against the catch 20, as shown in Fig. 6, the marker then being in the position shown in Fig. 4'. The extension 6 is clear of the liquid, will be manifest from an inspection of Fig. 4, and at the time the marker is arrested the loopholder J has not reached the position shown in Fig. 2. As it continues its outward movement, however, the cam edge 2 1 engages the catch and gradually swings the latter outward onto the flat portion 25, thereby withdrawing the catch from the collar 19 and permitting the spring 15 to complete the retractive movement of the marker into the reservoir. Such final retraction is so slight, however, and the extension 6 is so near the surface of the marking liquid when. it occurs that no splashing or spattering takes place, the effect of the retardation or arrest of the retraction of the marker being to cause it to dip quietly into the liquid.

My invention is not restricted to the precise construction and arrangement herein shown, as the same may be modified or rearranged by those skilled in the art without departing from the spirit and scope of my invention.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a loop-banding machine, a marker to mark the band, means to actuate it, a reservoir to contain marking liquid into which the marker is adapted to dip, and means to govern and retard retractive movement of the marker into the liquid, whereby splashing of the latter is prevented.

2. In a loop-banding machine, a marker to mark the band, means to actuate it, a reservoir to contain marking liquid into which the marker is adapted to dip, a spring to retract the marker, and means to retard such springholding and twisting instrumentality includ- 7 ing a movable loop holder, an oscillating marker, a reservoir containing marking liquid into which the marker dips, means governed by the movement of the loop-holder in one direction to swing the marker against the band to mark it, a retracting-spring for the marker, and means governed by opposite movement of the loop-holder to retard the retractive movement of the marker and thereby prevent its sudden entrance into the liquid.

5. In a loop banding machine, a band holding and twisting instrumentality including a movable loop holder, an oscillating marker, a reservoir containing marking liquid into which the marker dips, means governedby the movement of the loop-holder in one direction to swing the marker positively against and to mark the band, a spring to retract the marker, a stop to arrest such retraction before the marker dips into the marking liquid, and means to withdraw the stop from arresting position by or through the movement of the loop-holder, to permit themarker to enter the marking liquid without splashing.

6. In a loop-bandin machine, an instrumentality to hold and twist a band, combined with band-marking means, including a reservoir to contain marking liquid, a marker to mark the band while in the said instrumentality, means to effect ositively operative movement of the marker, a spring to cause retraction of the marker and dip it into the marking liquid, and means governed by or through said holding and twisting means to interru t retractive movement of the marker an prevent the same from dipping suddenly in the marking liquid.

7. In a loop-banding machine, a movable loop-holder,'twisting means for the band, a swinging marker, a reservoir to contain marking liquid and into which the marker is adapted to dip, means actuated by or through movement in one direction of the loop-holder to operate the marker and mark the band, a spring to retract themarker as the loop-holder moves in the opposite direction and means to interrupt such retractive movement before the marker enters the reservoir and thereafter to ermit the marker to dip easily into the mar ring liquid, to prevent splashing thereof.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
